Coupling element for two plugs, adapted male and female elements and coupling device obtained

Abstract

The subject of the invention is a coupling element for two plugs comprising a body (18) provided with: a first base impression (24) arranged in said body, a terminal housing (34) able to receive an insert (32) in which is created a second base impression (30), a third connection impression (36) derived from the first impression and emerging in this terminal housing, and a contact-bearing connection block (32). The invention also covers the necessary male and female elements as well as the coupling device obtained.

What is claimed is: 
     
       1. Coupling element for two plugs comprising: a body (18) provided with: a first base impression (24) created in said body;   a terminal housing (34) created in said body;   a third coupling impression (36), derived from the first impression and emerging into the terminal housing;     an insert (32) received in said body (18) and located in the terminal housing (34), the insert having a second base impression (30); and   a contact-bearing connection block (38) connected to the body (18) and having a frame with a section (102) located in the third coupling impression, and electrical contacts (108) located on the frame, the section (102) being sandwiched between the body (18) and the insert (32).   
     
     
       2. Coupling element according to claim 1, further characterized in that contact-bearing connection block (32) has guiding and positioning means (102) of conjugate profile to that of third impression (36). 
     
     
       3. Coupling element according to claim 2, further characterized in that connection block (38) has a general T profile. 
     
     
       4. Coupling element according to claim 2, further characterized in that connection block (38) has a general Z profile. 
     
     
       5. Coupling element according to claim 1, further characterized in that the contacts (108) of the connection block are strip contacts. 
     
     
       6. Coupling element according to claim 1, this coupling element being provided to be mounted across a wall (12), further characterized in that the coupling element comprises means (22) for attachment of body (18) onto said wall, said element then crossing over. 
     
     
       7. Electrical coupling device comprising a female/female double coupling element according to claim 1, as well as two male plugs having a complementary profile to that of the first (24) and second (28) base impressions, characterized in that the plugs and base impressions (24,28) have complementary latching means comprising an elastic locking catch (82) borne by each of the plugs provided to cooperate with a protrusion (58) manufactured with each of the impressions, guiding and polarizing means (50, 72) for the plugs as well as protection wings (86) for the elastic catch borne by the plugs. 
     
     
       8. A coupling element as in claim 1 wherein the frame comprises a second section which extends into the terminal housing. 
     
     
       9. A coupling element as in claim 8 wherein the second section extends into the second base impression. 
     
     
       10. A coupling element as in claim 9 wherein the frame comprises a third section which extends into the first base impression. 
     
     
       11. An electrical connector coupling element for connecting two plugs, the coupling element comprising: a body comprising a first receiving area, a second receiving area, and a third receiving area;   an insert connected to the body and located, at least partially, in the third receiving area, the insert comprising a fourth receiving area;   a contact-bearing block connected to the body, the block comprising a frame and contacts mounted to the frame; and   wherein a first section of the frame is located in the fourth receiving area, a second section of the frame extends into the fourth receiving area, the contacts extend into the first and first receiving areas, and the first and fourth receiving areas are generally sized and shaped to matingly receive the plugs.   
     
     
       12. A coupling element as in claim 11 wherein the body comprises a one-piece member. 
     
     
       13. A coupling element as in claim 11 wherein the frame of the contact-bearing block comprises a general Z shape. 
     
     
       14. A coupling element as in claim 11 wherein the frame of the contact-bearing block comprises a general T shape.
